چکیده

Purpose: Tumour cells produce energy through glycolysis and lactate dehydrogenase (LDH) is a key part of glycolysis. Elevation of serum LDH may indicate poor prognosis in primary duodenum adenocarcinoma. We aim to explore the prognostic significance of LDH in this disease. Methods and materials: Two hundred forty-four patients diagnosed with primary duodenum adenocarcinoma who were treated at the Sun Yat-sen Cancer Center from February 1996 to January 2016 were retrospectively analysed. We collected routine clinical data, including baseline LDH. Patients were classified into a normal LDH group (≤ 245U/L) and higher LDH group (>245U/L). Correlations of the LDH level and other clinicopathological characteristics were explored using the Chi-square test. Prognostic factors for overall survival were identified using univariate and multivariate analyses. Results: Two hundred seven patients (84.9%) had normal LDH levels, while 37 patients (15.1%) had abnormally high LDH levels. Higher LDH levels were significantly associated with more distant metastasis, node metastasis, poor differentiation and TNM stage Ⅲ-Ⅳ (P<0.05). Consistently, patients with node metastasis, poor differentiation and TNM stageⅢ-Ⅳ had a significantly higher median LDH level (P<0.05). The median survival of patients in the higher LDH group was significantly shorter than that of the patients in the normal LDH group (16.3 m vs. 42.5 m, P=0.02). Using multivariate analysis, LDH, age and radical surgery were independent prognostic factors associated with overall survival(OS) (HR=1.571, P=0.036 for LDH; HR=1.514, P=0.013 for age; HR=0.248, P<0.0001 for radical surgery, respectively). Conclusions: For the first time, our research suggests that baseline serum LDH is an independent prognostic factor in primary duodenum adenocarcinoma patients and elevated baseline serum LDH indicates a poor prognosis.

The levels of Serum Alkaline Phosphatase and Lactate Dehydrogenase in Hodgkin Lymphoma

Background: Hodgkin’s disease (HD) is a neoplastic disease originating in lymphoid tissue, which spreads to lymphoid structures and ultimately nonlymphoid tissues. Lactate Dehydrogenase and Alkaline Phosphatase are increased in blood following membrane cell damage. The aim of this study was to compare Lactate Dehydrogenase and Alkaline Phosphatase levels in children in different stages of Hodg...

Objective: Meningitis is life-threatening condition and examination of the Cerebrospinal fluid (CSF) may not give a precise diagnosis and prognosis of different types of meningitis. Bacterial meningitis is still a very common problem especially in many developing countries. The aims of study are to estimate the importance and significance of Lactate Dehydrogenase (LDH), protein...

Serum lactate dehydrogenase predicts prognosis and correlates with systemic inflammatory response in patients with advanced pancreatic cancer after gemcitabine-based chemotherapy

Serum lactate dehydrogenase (LDH) concentrations correlate with tumor progression and poor outcome. We evaluated the predictive value of serum LDH level for overall survival (OS) of patients with advanced pancreatic cancer after gemcitabine-based chemotherapy. We retrospectively enrolled 364 patients with locally advanced or metastatic pancreatic adenocarcinoma who were then allocated to traini...
